Wellcraft Boat Owners Forum

So I've been scouring the internet trying to find an answer to my question, and then I found this forum. After searching here for a bit I still haven't found an answer.

So here goes:
1979 WellCraft SunCruiser 2000
Is the hull solid fiberglass or is it cored with something, like foam.
I am looking at an in-hull transducer for my fish finder, but apparently they only work on solid fiberglass hulls.

Please help!
I'd love to get my transducer off the transom and out of harm's way. Plus it should increase the speed at which I can fish find.

I not 100% sure but I don't think that hull is cored

Early 80s were solid fiberglass, I know Thompson’s were plywood cored hull, Boat salvage yard might be able to give answer on suns

Thanks!
